I got my 602 kit in the mail a few days ago and it seems to be the best PV I've tried yet for dipping. The flavor of about 3 drops on the wick with an empty cart shell on this device is pretty intense.
I do seem to be having some issues with my batteries, though. Maybe it's just the charger that they sent with my shipment? Instead of having the typical red and green led's on the charger, it's just one blue led. I have left batts connected to this charger overnight and the charger still claims that it's charging the batt. The batt will work for a short period, then blink and claim it's out of juice. Another batt from the batch seems to have lasted almost forever without needing to be topped off. Now that I read what I just put down, it sounds more like one of my batts is faulty. I will mark the batts with tape so I can track down which one is giving me fits.
I do find that the draw on the 602 is a WHOLE lot stiffer than any other PV I've tried yet. I used to pack down my American Spirit cigs pretty tight, and it never had a draw this hard. It's not really a bad thing, just a difference. Also, when using a cart, the vapor it produces tastes very "plastic-y". I can't quite figure out why. If I take the juice-holding doohickey out of the cart and try again, the flavor is amazing. I can see myself figuring out a way to dip while on the road just for the flavor that this guy produces, though.
All in all, I'm very satisfied. Now I just want my KR808D1 to arrive and I should have enough of a PV collection. For now. Until I try some mods...
